soN, a subject of the King of the United Kingdom of Great Britain and Ireland, and

a resideht of Ann street, Brisbane, in the.

State of Queensland, Commonwealth of Australia, have invented a certain new and useful System for Electrically Releasing any Number of lDrawers 'in Cash- Registers, Money-Tills, and the Like, of which the tollowing is a speciiicatio'n. y i This invention relates to the working of any number of drawers attached to or forme ing part of cash-registers, money-tills, and the like, its object being to provide an electrical system whereby the drawer cannot be opened except by pressing the corresponding initial or salesmans key in combination with the'operating or release key of the machine gr by turning the handle which operates the ther 'mechanism of the machine. The invention consists in iiXing' to the casing of the machine contact-springs which engage with the`v initial-keys, which when pressed down make contact with insulated screw-pins'iixed lin the face of the machine'.

From the screw-pins line-wires are carried to electromagnets and from them to a battery, the other pole cf which is connected by a wire to an insulated screw-pin, which makes contact with a contact-spring by pressing down the operating-key, thus completing the circuit by the metallic casing of the machine, or the 'circuit may be completed by a wire ixedy to the screw-pin, with which the contact-spring makes contact on the operatingkey being pressed down or the operating-lever revolved, and to all of the screw-pins to which contact is made on pressing. down one of theinitial-keys. A simple lever or catch holds the drawer closed, which when released .is pushed outward by a spring.

To fully describe the invention, I will now refer to the drawings, in whichvFigure I'4 illustrates the general arrangement of the electrical system as connected to a cash-register machine fitted with two drawers, part of which is shown in section.

A is the face of a cash-register; B, B', and B2 initial or salesmans keys, and C operat- Aing-key; t, b', and b2 contact-springs which engage with the initial-keys, and `c contact-` Y spring with which the operating-key engages. These springs when the keys are pressed down make 'contact with the screw-pins d, d', d2, and (Z3, insulated electrically from the machine.

E and E' areI the line-wires from the insulated screw-pins d and d' to the electromagnets G and G', and F the common returnwire to the battery H, the other pole of which is carried by the wire F' to the screw-pin d3.

I and I' are catches, which may be of any suit-able pattern, mounted upon suitable pillars at the center and held in engagement with the catches J and J', attached to the vend of the drawers by spiral springs K and K.

M andM' are coil-springs for pushing the drawers out when released by the attraction of the electromagnots G and G' on the armatures attached to the catches I and I'.

N and N' are the drawers, to which are fitted rollers or wheels fn. and n' to overcome friction in travel.

I have described the system in connection with aV battery; but I would have it understood that the electric current may be taken from an electric light or any other electrical service.

This system of operating a number of drawers is applicable to machines ofthe "National type, when either a handle o r lever is used for operating `the machine, or to the Union" 'type of machine, w'here a special operating-key is used to 'release the mechanism of the machine.

The first contact made by pressing down one of the initial-keys is a permanent conby operating the machine; but the second contact made by pressing down. the operating or release key Aor revolving the crank is only momentary, which instantly completes the electrical circuit, thus operating the detent tact, the key being held down until released l IOO magnetic devices an initial-key, a normally In witness whereof have hereunto set my open svtotlll in said circuit ar'lcanged be handn-presencevof two Witnesses.
